A similar interface was published at the CHI 2003 conference (see: http://www.monzy.org/urinecontrol/).
I'm pretty sure it was published as part of "ALT CHI", which always has many strange human-computer interfacces including 'bed' interfaces for remote presence in bed, and things like EUI's or "Edible User Interfaces" (see the EUI proposal by the same researcher on the above website).
